We produced the highest possible temperature using the OCCT v2.0.1 software with a custom 30mins (mixed) operation.

We left both CPU cores running at full load for 30 minutes. All
temperatures were logged using the CoreTemp 0.99.3 and the software itself. We took the measurements with the CPU running both at at stock speeds and under overclocking:

Intel Core i7-920 @ 2.66GHz

Vcore: 1.1000V

Other BIOS values: Auto

Intel Core i7-920 @ 3.60GHz

Vcore: 1.26250V

DDR3 Voltage: 1.66V

Other BIOS values: Auto

For the noise tests we used a Precision
Gold N09AQ Environment Meter. All measurements were made at 30cm distance from the cpu cooler running at full speed.
